Introduction
We prefer that your Trilogy dealer delivers, installs, sets up and explains your 909’s operation to you.
However, we still recommend that you read through this manual thoroughly and keep it to hand for reference if
you intend using some or all of the 909’s complex and rather unique features.
Should any part of this manual or the operation of the 909 not be clear to you, please do not hesitate to contact
your Trilogy dealer. If they are not available please contact ourselves directly.
About this manual
Throughout this user manual, the following icons are used:
[enter] This refers to a physical control on the 909.
RETURN 1 This refers to a physical connection on the 909.
Bal Centre
This indicates information that is presented on the display.
From this point on, any information presented on the left hand pages are pictorial representations of either the
front or back views of the 909 or of the display.
Therefore consider the left hand pages as additional information to accompany the written descriptions on the
opposite pages.

Unpacking
Be careful when unpacking your Trilogy amplier, it is heavy. Seek assistance if necessary. Store the packaging
safely for future use. It is the ideal method of protecting your amplier from damage during transport.
Environment
Do not site the amplier near liquids, or place water-lled containers near the unit. If water does come into
contact with the unit there is serious potential for an electric shock or re hazard. Immediately pull out the mains
plug from the wall socket. Contact your dealer to arrange an inspection before further use.
The amplier is cooled by convection and so needs good circulation of room temperature air under and around it.
Do not place it near sources of heat such as radiators or in direct sunlight. Do not enclose in a cupboard. Do not
place directly on carpet.
A at, smooth surface is required. As with all high resolution audio equipment, your amplier is sensitive to
vibration, strong magnetic elds and radio interference. A dedicated high performance equipment platform sited
away from other appliances is the optimum location.
Power Supply
The AC input voltage has been set for the country it was purchased in. Check that the label on the rear panel
matches your AC supply voltage before plugging in. The AC inlet cable provided should be used. If another cable
is used check it is wired correctly. The fuse should be rated at 10 amps.
The wires in the AC input cable supplied are coloured in accordance with the following code:
Green and yellow..............Earth
Blue................................Neutral
Brown.................................Live
The amplier must be earthed. Do not disconnect the AC earth at any time. If in doubt about any aspect of
power supply, consult your Trilogy dealer or a qualied electrician.
A direct connection to a mains outlet is best for your amplier, avoid adapters. To realise your amplier's full
potential we recommend high quality mains conditioning. See www.Isol-8.co.uk for more on power supply and
system solutions from our highly acclaimed sister company.

Connections
It is good practice to complete all interconnections before switching on to avoid any damage to your system's
loudspeakers while plugging in.
The IEC inlet provides the unit with power. Connect with the supplied AC input cable. It can be left connected at
all times to ensure reliable operation. If not being used for extended periods of time switch off at the mains outlet.
See the Comprehensive Operation Guide for timed, sleep and remote switching.
The Pre-Amplier can accommodate six line level audio inputs. Two are associated with auxiliary loops. If both
loop functions are not required RETURN 1 and RETURN 2 can be regarded as inputs 5 and 6. Connect your
sources to these inputs via RCA phono cables as required. A separate phono stage will be required for vinyl
playback.
Two sets of main line level outputs are provided. Connect MAIN 1 to your power amplier via RCA phono cables.
MAIN 2 is provided for connection to a second power amplier for applications such as bi-amping. MAIN 2 is not
independently buffered or controlled.
Two independent switchable auxiliary loops are provided, SEND 1 and SEND 2 with RETURN 1 and
RETURN 2. These can be congured to provide send and returns to and from recording media, AV or multi-room
systems independently from the main outputs. They are congured via the front panel controls as detailed in the
Comprehensive Operation Guide.
Twin TASLink connectors allow interconnection, control and monitoring of other Trilogy Audio System products
via QuietBuss technology. The associated LEDs give status information. The Comprehensive Operation Guide
contains further information. TASLink cables are available from your Trilogy dealer in various lengths.

Security
Each 909 comes with its own unique PIN for your security. If the AC input is disconnected for a long period of
time you will be prompted for a PIN on power up. Please take precautions to remember your PIN and make sure
it cannot fall into the hands of others. Should you not be able to enter the correct PIN, contact your Trilogy dealer.
PIN Code Protection
When the amplier is rst powered, or unplugged for approximately fteen minutes, the pre-amp requires a
security PIN code to be entered. When the display says
PIN Code
, press [enter] and the display will read
00----
where 00 are the rst two digits of the PIN code you are entering. Set these digits correctly with the
[shaft encoder], noting you can move backwards through 00 to 99 for speed. Press [enter], adjust the next pair of
digits, [enter] to change the last pair then [enter] again to complete PIN code entry.
If the PIN is entered incorrectly, press [enter] at the warning but note after three failures, the unit will be locked out
for two minutes before prompting again for PIN entry.

Powering the Pre-Amp
Once the PIN code has been correctly entered, the pre-amp can be powered using the [power] button. The
message
Warm up...
will be displayed while the circuitry warms up, and any attached power amps warm up if
they are controlled from the pre-amp. After forty seconds, the pre-amp is unmuted, the current input and volume
are displayed before the menu defaults to the home page.
Turn off by again pressing the [power] button, which includes the ability to abort power up during the warming
period. The message
Turn off
is displayed and this takes a couple of seconds as outputs are muted before
valve circuitry is powered down.
This simple on/off operation is the standard setting from the Trilogy factory, but the detailed menus offer the ability
to select an intermediate
Standby
mode, where a simple press of the [power] button while powered places the
pre-amp and peripherals in a keep warm mode. This is of particular benet for equipment such as the 990 power
amplier, which can cycle power to its circuitry to keep warm, while reducing power consumption below standard
mute modes. When this mode is enabled, full turn off is achieved by pressing and holding the [power] button.
Quickstart
Having made and checked all appropriate input, output and AC connections, press the [power] button. The unit
will remain muted until warm up is completed.
Select an Input from [1] to [6] . The [shaft encoder] will adjust volume.
To explore the control menus use a combination of [shaft encoder], [escape] and [enter] buttons. The display will
be your guide. If you get lost, press the [escape] button repeatedly until the originally selected input is displayed.

Overview
The Trilogy 909 pre-amp offers a nested menu structure to access the large number of options. This is intuitive,
using a combination of [enter] / [escape] buttons and the rotary [shaft encoder]. Although the six input select
buttons could have been used at some point in the menu structure, this would have been difcult to remember.
The six input buttons are only ever used to change the input you listen to, which may also be associated with
input level adjustments (trim).
By default, the pre-amp displays what we call the ‘Home Page’, which is selectable as a blank screen, Trilogy
logo, time, input or volume. The home page can be set differently when the pre-amp is off, compared with when
it is powered.
Navigating the menu, you will alternate between the [enter] button and rotary [shaft encoder], with [escape] to
step back up one level. Because the [shaft encoder] is normally used to adjust the volume from the home page,
the rst step to access the menus is to press [enter], which shows the record output. This can be changed with
the [shaft encoder], or [enter] again to adjust balance. [enter] again for brightness and choose from automatic
according to ambient light, or xed levels 1-9. The next [enter] will display
More
, which is the route into the
detailed menus, which are accessed by turning the [shaft encoder].
The top level menu is circular, so pressing [enter] when
More
is displayed will return to record output selection.
[escape] at any time from these top level settings to return to the home page, and press [escape] from the home
page to display the current time. Holding [escape] for several seconds at the home page will display the unit’s
serial number.
You will nd it intuitive, but it is unusual that you advance between top level menus of output, balance, brightness
and more using the [enter] button, whereas in the detailed menus found within
More
, the different menus are
selected with the [shaft encoder]. The logic for this is we nd it acceptable to select between the small number of
high level menus using [enter], and also that each of these top level menus demands the use of the
[shaft encoder].
To access the detailed menus,
More
should be displayed then turn the [shaft encoder] to select between time,
defaults, names and tools. If you have enabled menu lock in the defaults (disabled by default), on turning the
[shaft encoder] you will be prompted to enter the four digit menu PIN code provided with your pre-amp. This is a
different number to the six digit PIN entered when power is applied.

More / Time
This includes setting the current time and sleep time similar to that found on an alarm clock, putting the pre-amp
to sleep after an adjustable number of minutes. On and off timers are provided for every day, plus global on/off
timers that apply every day. Individual timers can be disabled and only some timers used if required. For example,
turn on Saturday morning and turn off Sunday evening. Press [enter] to access
Sleep
, then select other time
options if required.
More / Time / Sleep
Pressing the [enter] button when
Sleep
is displayed, will allow the user to set a sleep timer to turn the pre-amp
off automatically after a set time. However during this countdown period the front panel button, an external
remote or one of the timers might switch the pre-amp off rst.
The default value displayed is
Off
, but using the [shaft encoder], the time can be adjusted from
0:01
(one minute until sleep) to
2:00
(two hours until sleep) in one minute steps. Once set as required, [escape] from
this menu or leave the display timeout to return to the homepage if enabled. When the unit goes to sleep, by
default it will switch off both the pre-amp and any TASLink attached peripherals.
If display timeout is not enabled and you stay on the sleep display, you will see a live countdown. If you wish to
disable the sleep timer, set it to
Off
.

More / Time / Timers
Timers are provided to allow automatic on/off switching customised to your daily routine, like a modern central
heating controller. This facility may be useful simply to bring your audio equipment to optimum temperature
before listening, to minimise power wasted overnight in maintaining temperature, or to provide wake-up music
like an alarm clock.
[enter] from
Timers
to show the ‘on timer’ for Monday, designated with the lled square top right of the display.
The day will be ashing. Turning the [shaft encoder] to the right shows the off timer for Monday with an empty
square bottom right, then on/off for every day with the addition of ‘all on’ and ‘all off’ timers which will work
every day.
The timer hours are adjustable
00
to 23, minutes are 00 to 59 as expected. We deliberately prevented the
[shaft encoder] ‘wrapping round’, eg 23 hours to 00 hours. Before 00 hours, there is an additional setting of
><
hours which disables that timer. Trilogy 909 pre-amps are shipped with all timers disabled and minutes set
to 00, that is
><:00
.
To adjust a timer, select the timer of interest with the [shaft encoder] and press [enter]. This allows hours to be
changed, including disabling with a setting of
><
. Press [enter] to edit the minutes or [escape] back to selecting
the different days on/off. It will be clear what you are changing with the [shaft encoder] as the display will be
ashing.
We have included what we hope is a useful feature. After editing timer minutes, pressing [enter] moves to the
next timer – press [enter] to edit that. This speeds setting as you are likely to edit an off timer when you have
edited that day’s on timer. However if you edit the minutes on one timer and do not want to edit the next timer,
simply press [enter] then choose another timer, or [escape] again to leave the timer menu.
The timers were designed with exibility in mind. Day timers do not have to be used in on/off pairs, so you could
have your system switch on Saturday morning and keep warm until Sunday evening, just using Saturday on and
Sunday off timers. Similarly, each day could turn on at different times, but the All off timer would switch off the
system at the same time every day.
When the unit switches off, it will switch off both the pre-amp and any TASLink attached peripherals.

More / Time / Time Set
An internal clock allows the pre-amp to operate its on/off timers and display the current time if required. The
clock must be set by the user but, once the time is set, it keeps time even when there is no mains power applied.
This clock offers the same accuracy as typical quartz units that are not locked to a time reference such as the
internet or a radio signal. As for similar devices, the clock may need adjusting occasionally.
To adjust or set the clock for the rst time, press [enter] at the
Time Set
menu. The day and time will be
displayed with the day ashing. Use the [shaft encoder] to adjust the day, [enter] to make the hours ash and
adjust (always 24 hour clock), then [enter] again to adjust minutes. [enter] will cycle back to adjusting the day.
Although seconds are not displayed, internally they are reset to zero if the time is adjusted.

Each step is 0.5dB.
Start
default volume level every time the pre-amp is turned on, unless the default input is
set to be a lm input, for example from a surround processor.
Max
maximum volume level that can be achieved for all inputs except any designated
lm input. This is useful when you don’t trust others with your speakers! It is
possible to increase the effective volume beyond this setting by adjusting the input
trim. If the maximum setting is reduced below the startup setting, when [escape] is
pressed the startup level is automatically lowered to match.
Film
nominally unity gain for surround systems where an input has a xed volume level
and all adjustments are made on the surround processor. The audio performance
of the Trilogy 909 pre-amp benets from the lack of closed loop control of the pre amp gain, hence the gain will vary depending on the valves. This setting allows ne
tuning of the unity gain, or adjustment to a value which is not unity.
With
Trim, Start, Max
or
Film
displayed, press [enter] to view and change the setting with the [shaft encoder].
Note that when you press [enter] to adjust all but trim, the pre-amp volume will change to the setting which you
want to edit, so you can audition the level correctly. For
Max
in particular we recommend caution. Press [escape]
to leave the menu and the new value is saved.

More / Defaults / Input
With
Input
showing, press [enter] to see the input that is selected every time the pre-amp is turned on with the
[power] button, timers or externally via TASLink. Options are the six inputs or
No input
selected at power on. The
default startup volume will also be selected at power on, unless that input is designated as the lm input typically
connected to a surround sound processor. In that case the default lm volume is used. Hence menus associated
with default input are defaults / volume and defaults / lm in. Factory default is input 1 selected at power on.
Changes to this setting will only be evident next time the pre-amp is turned on.
More / Defaults / Film in
If an input is designated here as the ‘lm input’, it has its own setting for volume which over-rides the volume
control and the volume is automatically changed to that setting when the lm input is selected. This level is set
in defaults / volume / lm. When listening to a ‘normal’ stereo input after the lm input, volume is restored to the
default startup volume set in defaults / volume / start.
No Film
is the factory setting for this parameter. To change this, press [enter] when
Film
in is displayed, then use
the [shaft encoder] to select the lm input. To avoid the volume jumping between the stereo and lm volume
settings as you pass over the currently selected input, changing this setting has no direct effect. Once an input is
assigned as the lm input, it must be deselected if already selected, then selected to enter the lm mode.
More / Defaults / Output
The default output is selected when power is applied to the pre-amp. The pre-amp does not have to be turned
on. This operation is quite deliberate. Whether the pre-amp is on or off, it was felt important to maintain the
currently selected record source so a recording can continue. The record output is maintained in all standby or
off modes, dependant only on mains power being available. This setting differs from the default input which is
selected every time the pre-amp is turned on – the default output is only selected when mains is connected.
Although applied at different times to the default input, changes are made in the same way, with options of
No output
or any of the six inputs.

More / Defaults / Balance
Default balance is similar to default startup volume as it is applied every time the pre-amp is turned on. Default
balance is not used in lm mode and can only be auditioned if the selected input is not designated as the lm
input. Similar to adjusting default volumes, when default balance is adjusted the pre-amp follows changes for
proper auditioning.
Factory default balance is
Bal Centre
which will be displayed when you press [enter] from
Balance
. Adjust
balance using the [shaft encoder] from the greatest left bias
<30
to a right bias of
>30
. The default balance can
not be adjusted to fully mute left or right speakers, a feature which is only available on the ‘live’ balance control
to check for faults. For those interested in dB, each step is 0.5dB where the volume adjustment permits – if the
volume is near minimum or maximum levels, the balance control will be limited in the range it can achieve.
Although volume can be displayed in dB or 0..99, balance is displayed as a number only.

When the
dB or 0..99
volume option is set to decibels, maximum volume is 0.0dB. Lower volumes are shown
as a negative value, e.g. -10.0dB is 10dB below the maximum possible level. This mode will suit those with a

More / Defaults / Warm Mode
By default, warm mode is off. When enabled, a short press of the [power] button turns the pre-amp on, a shortpress puts it into warm mode, a long press from on or warm will turn the equipment off. For the 909 pre-amp
alone, warm mode simply mutes the amplier and is not of great benet. This facility is really intended for use
with equipment such as the 990 power amp that has a true ‘keep warm’ mode. When connected via TASLink,
placing the 909 pre-amp in warm mode will maintain a steady temperature for the 990 power amp heatsink.

This menu allows changes to TASLink settings for bus power, bus remote GPI and high speed data. We suggest
you read the TASLink overview before changing these settings.
Bus power
Bus power can be turned on or off. It is on by default.
The bus must be powered by the pre-amp or another Trilogy power source for the
low speed bus to operate
Bus remote
The bus remote line is one pin of the TASLink connector and is used to turn on
Trilogy, or other manufacturer’s, equipment that is not equipped with the TASLink
low speed bus. Alternatively, the bus remote line can be an input to the 909 pre amp to allow turn-on from other systems. Options are,
Not used

suitable devices being connected.
More / Names / Inputs
The pre-amp leaves the factory with input names set to Input 1, Input 2 etc. These names can be edited, for
example to show the equipment type such as CD or Tuner. Names are limited to ten characters, but it is possible
that not all characters will t on the display. We use variable width fonts on the display to improve the look,
meaning a capital “B” is much wider than a lower case “i”. Using variable width fonts actually increases the
number of characters available on the display but it does mean the characters available depends on what you
want to display.
With
Inputs
showing, press [enter] and the display will show the input number and name of the rst input,
1Input 1
, where the rst character will be ashing. At this stage you can select which input name to edit with
the [shaft encoder]. When the desired input is displayed, press [enter] again and the rst number will disappear to
show the input name as it will appear in normal operation,
Input 1
.
Again the rst character is ashing, but now it is ashing on the rst character of the name which can be edited
using the [shaft encoder]. Pressing [enter] moves to the second character, and so on through all ten possible
characters before returning to the rst character. Each ashing character can be changed with the
[shaft encoder]. There is no delete function, so simply set that character to a space which is found by turning
the [shaft encoder] fully anticlockwise. Because it would be impossible to see a ashing, blank space, if you are
editing a character that is a space, a dot ashes at the top of that position.
Ten characters are allowed, even if they do not all t onto the display. If you change characters near the beginning
of the name, you may nd end characters come into view, but if they are out of view during editing they will not
be seen during normal operation. We could have scrolled the display for you to edit end characters otherwise
off the display, but our method means you will not waste time editing a long name only to nd it does not t in
normal use!
Pressing [enter] to cycle through the characters applies even when the characters are off the end of the display.
You may need to press [enter] a few times without seeing a ashing character before returning to the rst
character ashing.

Shipped from the factory, equipment such as the Trilogy 990 power amp will turn on and off, following the
909 pre-amp if connected over TASLink. There is no need to name devices that are controlled over the TASLink
low speed bus, but naming allows their status to be checked through the display of the 909 pre-amp. This status
includes running temperature and fault messages. Naming devices also allows their serial number to be checked
remotely.
To allow TASLink communication, each device controlled via low speed bus needs a unique ID number. From the
factory no ID number is set on such equipment as the 990 power amp.
This menu intelligently combines the assignment of ID numbers and the naming process.
When rst run with new equipment, pressing [enter] on this menu will display
01.
where 01 is the ID number and the dot means no device has responded. Use the [shaft encoder] to select ID 02,
03 etc. to a maximum of 24.
We suggest you use contiguous ID numbers starting from 01, as unit 01 is the rst status that is fetched in that
menu. With 01 (or other) displayed, low speed bus units should have their front panel LEDS mostly off with
a short ash on. This indicates the button is temporarily not used for on/off and can be used to ‘grab’ an ID
number from the pre-amp. If you need to switch off the devices during this time, for example due to excessive
audio levels, use the pre-amp power button to switch off both the 909 pre-amp and connected devices.
A two second press of the power button of equipment such as the 990 power amp, will cause that device’s LED
to change from an occasional ash to rapid ashing, to indicate it has taken the current ID. With multiple devices,
it is possible to move between ID numbers 01,02 etc. using the [shaft encoder] and device LEDs will change their
ashing to indicate which is being addressed. Grabbing an ID number where that ID number is used elsewhere,
will cause the original device is automatically reset to having no ID number, just as it leaves the factory.
Once a device has an ID number, it will return with the factory name e.g.
01990
and names can be edited in
the same way as input naming. Press [enter] and
990
will be displayed with the rst character ashing. Edit the
name, using [enter] to advance through the characters and [escape] to save. There will be a short delay showing
01.
again while the name is written and read back over the TASLink low speed bus.

Tools offers detailed system information – TASLink peripheral status, a ‘health check’ for the TASLink bus itself,
and a check of software versions in the pre-amp and peripherals. Tools also allows presets to be returned to the

To protect your investment in Trilogy equipment, this facility allows many Trilogy peripherals to be security bonded
to the 909 pre-amp. The Trilogy 990 power amp is one example that, once bonded, can not be turned on with
its local power button or via TASLink other than with the original bonding 909 pre-amp. With target peripherals
connected to TASLink, press [enter] and the message
Done
will be displayed. To prove bonding has been
successful, power off equipment such as 990 power amps, either with their front panel buttons or via the 909
pre-amp. Then attempt to power peripherals with their front panel buttons which should not work if bonding has
been successful.
Please note there is deliberately no indication which 909 pre-amp is bonded to different power ampliers etc.
This is a security issue.
More / Tools / Unbond
When reconguring your system or moving some units to a different location, there may be a need for bonded
equipment to be unbonded. Even Trilogy dealers are unable to undo security bonding and only the original
909 pre-amp can unbond those items which it has previously secured. After pressing [enter] and receiving the
message ‘
Done
’, front panel buttons should be used, like bonding above, to test whether equipment can be
turned on locally. In this case, it should now be possible to power peripheral equipment via their local front panel
buttons.
More / Tools / IR Code
Although Trilogy offer a very attractive PRC Infra Red remote control, some users will want to use programmable
remotes to cover different types of AV equipment. Although some programmable remotes are very capable,
experience shows that some can be complicated to setup. The standard factory setting for the 909 pre-amp is
Philips’ RC5 remote control standard with a system code of 16 (10 hex). Remote numbers 1-6 are the six input
buttons, 7 is [escape] and 9 is [enter]. Digit 0 opens external status, program up and down navigate the menu
in a similar way to the [shaft encoder], while volume up and down are as expected – menu and volume are
separate functions, unlike the front panel [shaft encoder]. Mute on/off is standard, while Time is the button used
for Teletext in television systems.
To aid fault nding with your remote control, the
IR Code
page shows a four digit hexadecimal number for the
IR code received. When nothing is received it shows
IR 0000
. If it continues to show this despite you sending
Infra Red commands, then those commands are not Philips RC5.

TASLink Overview
TASLink is Trilogy’s proprietary bus system offering power and data to remote displays, and also data to other
Trilogy audio products to synchronise power on/off and provide error information. TASLink has a bus remote line
(GPI) allowing equipment from other manufacturers to be powered on/off by the 909 pre-amp, or allow the 909
to be turned on by another system.
Standard Cat5 or Cat5e cables are used, the same as used for computer networks with RJ45 plug terminations.
Do not however cross-plug computer networks and TASLink, as damage may result. It should be noted that
Cat5/RJ45 cables are not unique to computer networks and are often used for telephony and other control
systems. The cross-plugging issue is not unique to Trilogy products and Trilogy can take no responsibility for
damage caused by failure to follow this instruction.
By using standard Cat5 wiring, users can take advantage of any structured wiring in their buildings.
Bus power
Nominally 10 Volts, bus power is used for external interfaces such as displays. The number of devices connected
to the bus should be discussed with your dealer, as larger systems may require a small additional power supply.
Even without displays, power is used by a number of audio devices that have internal optical isolators. Bus
power should not be connected to non-Trilogy equipment.
Bus remote on
This is a 10 Volt remote control signal for Trilogy equipment to power up, by starting their turn on procedure.
Usually output by the pre-amp and optically isolated in power amps, the pre-amp can be set to receive this signal
instead so a different system can deliver the main power-on signal.
High speed bus
This is a balanced data bus used for devices that require regular and fast communication with the pre-amp. An
example of this is an external display that needs to update many times a second when adjusting volume. This
bus uses industry standard transceivers to offer best performance over long cable length, but the message
format is unique to Trilogy. This bus normally operates continuously, but can be disabled in the master if there
are no devices that need it. Where TASLink loops through a device that does not use the high speed bus, bus
signals are looped locally between connectors and kept well away from audio.

909/um/20042014
Page 44

Low speed (quiet) bus
This quiet bus is proprietary to Trilogy, both electrically and in the messages that are sent. Developed to serve
audio devices that do not require fast updates, there are three optically isolated signals (LSS/LSW/LSD) which
allow the microcontroller in the audio device to turn off during normal use. The master can briey enable the
microcontroller in the audio device to power up/down, or the audio device can alert the master to a fault which
has automatically woken it from sleep. This bus operates infrequently and at 1/100 the frequency of the fast bus.
In normal operation the quiet bus will be completely silent.
Rear Panel LEDs
The use of the rear panel LEDs may change over time. Currently, they are used to indicate,
LED A Bus power on
LED B Bus remote on
LED C Bus LSS
LED D Bus LSW
LED E Local LSD
LED F Bus LSD
Diagnostics using LEDs C – F are possible, as part of Trilogy dealer training. You may be asked to look at these
LEDs as part of any telephone support.
Front Panel Warning LEDs
Dots to the right of the front panel display are used to indicate problems. The centre right LED will ash if TASLink
attached equipment capable of error reporting has a problem. Use more / tools / ext status to check which unit
has a problem. When looking at individual unit status, this LED will continue to ash for any units that would
produce this warning when on other menu screens.
The top two LEDs on the right will ash if the current drawn on TASLink bus power has exceeded the maximum
allowable, 500mA for more than one second or 1000mA for more than half a second.
Similarly, the bottom two right-hand LEDs will ash if the current drawn on the TASLink remote line has exceeded
the specication, which is the same as the bus power line. Bus power and remote overcurrent will result in that
output being switched off and mains power must be removed from the pre-amp to clear either of these faults.

Cleaning
Dust the unit regularly with a soft cloth or soft brush. For more stubborn marks make sure the unit is switched off
and disconnected from the power supply. Use a slightly damp cloth with a very small amount of mild detergent
such as washing up liquid. Do not use a wet cloth. Be careful when using cleaning or polishing agents. Never use
abrasives or alcohol based agents, they will harm the surface nish. Do not allow the unit to become wet when
cleaning.
Servicing
Your Trilogy amplier uses thermionic valves or vacuum tubes for amplication. They are the key component in
realising your ampliers very high performance. Valves have a nite lifespan and will need replacing during the
lifetime of the amplier. This lifespan depends on how long and how hard they are used. In typical use, small
signal valves can last for 5000 hours. Frequent switching on and off reduces valve life.
Please bear in mind that some failures can occur early on in a valve’s working life, usually due to mechanical
stresses that can occur during shipping. This is not a reection on the ampliers design but is an inherent
characteristic of all valves, and is impossible to predict even during the ampliers factory burn in period. The
good news is considerate circuit design and modern manufacturing methods mean that valves are now typically
very reliable once established in service.
It is good practice to replace the valves your amplier periodically to prevent sudden loss of a signal path. Your
Trilogy amplier uses readily available and inexpensive valves should replacement be needed. If you are in any
doubt your Trilogy dealer will help you assess whether your valves need replacing.
If your amplier exhibits noticeable loss of performance, extreme sensitivity to vibration or becomes excessively
noisy then new valves should be tted by your authorised Trilogy dealer.
There are no user serviceable parts inside. Do not open or attempt to repair the unit. Refer to your authorised
Trilogy dealer for servicing.
Declarations
